A few years ago, I had a Canon DSLR modified and used a B+W 489 IR blocking filter and a custom white balance so that I could take 'normal' photos. I also tried a 486 filter, which also worked well, although this is an interference filter and not suitable for wide angle lenses due to the angle at which the light comes in.

With a filter on, take a photo of a white sheet of paper and use that as the basis for a custom white balance template. You may need to do a few iterations to get it right. I had a few custom white balances - sunlight, cloudy, tungsten etc.

Unfortunately the camera was stolen - I wonder if whoever ended up with it managed to figure out why all the colours were so strange if they used a lens without the filter and white balance set correctly...
Thanks I did exactly that and it did work but can you believe I then sold the camera (and explained everything to the new owner). I am instead buying a QHY268C
